 MCP Virtual Labs Models
 =======================
 
-OpenStack Reclass models for Mk-based cloud deployments for QA.
+Virtual reclass models for MCP based deployments for Dev & QA purposes.
+
+Features implemented are expected to be backported to:
+- cookiecutter repository
+- system level reclass
+- formula default metadata

+Model validation
+================
+
+Models are validated on each commit with latest system-level reclass.
+
+Models can be validated locally in docker instance with test-kitchen. Resources:
+* https://github.com/salt-formulas/salt-formulas/tree/master/deploy/model
+* https://salt-formulas.readthedocs.io/en/latest/develop/testing-formulas.html#requirements
